1 ELECTRICAL NETWORK ANALYZER -MC 760 ELECTRICAL NETWORK RECORDER - MC 750 MULTIFUNCTION METER - MC 740 ENERGY METER - MC 720 POWER METER - MC 710 WE RECORD QUANTITIES OF ELECTRICAL NETWORK, MEASURE INSTANTANEOUS VALUES OF MORE THAN 140 QUANTITIES, MEASURE ENERGY AND POWER, CALCULATE ELECTRICITY COSTS BY TARIFFS

2 EN STANDARD The EN standard specifies the most important voltage characteristics of electricity supplied by public distribution systems and the limit values where such characteristics can be expected. EN specifies allowable voltage values at: 1.Voltage and frequency deviations 2.Voltage dips, interruptions and voltage unbalance 3. Harmonics and THD 4. Fast voltage changes MC 760 ELECTRICAL NETWORK ANALYZER - EN STANDARD Permanent analysis of power quality in compliance with EN Large memory capacity of the recorder: 8 Mb - reports for a period of seven years and 170,000 deviations from the standard values Optional setting of limit values of the electrical network characteristics MC 760 ELECTRICAL NETWORK ANALYZER - FINDING DEVIATIONS FROM THE EN STANDARD Frequency deviations Voltage deviations Voltage dips Voltage interruptions Voltage unbalances Overvoltages Fast voltage changes Flicker intensity THD Harmonics HANDLING THE COSTS - MC 760, MC 750, MC 740 A special function of the meter is energy cost evaluation (active, reactive, total) by tariffs.the meter enables tracing the energy costs in optional currency. Consumption is calculated by means of the adjustable tariff clock and electricity price by tariffs.
